HI.
I guess it is called "Tracks" in English version.
I use this tool for planning my MTB-tours, and it is good to have this functinallity. But I think the "exporer" of it is kind of basic.
1. Location should be saved, as my work office computer have its ISP far away, and returning from a "track" goes back to that location, "return to last view should be implemented".
2. I want to sort on date, in filter, as area were I am bicycling is changing due to forrestwork, making old tracks inpassable.
3. Also good to have when the "track" have been uploaded/created.
4. More info like, who have made the track, good if you find tracks made by same person.
